RADIO CONTROLLING DEVICE Filed July 7, 1930 Patented June 5, 1934 UNITED STATES PATENT ()FFICE' 3 Claims.

This invention relates to radio controlling devices and has for its object to provide a new and improved device of this description. The invention has as a further object to provide a controlling device for radio apparatus which will automatically start and stop the radio apparatus responsive to controlling means at a distant point.

It often happens, for example, that the party using a radio apparatus will desire to make a telephone call while the radio apparatus is in operation, and the sound produced by the radio apparatus interferes with the hearing of the telephone messages.

This invention has as a further object to provide means for automatically shutting 011 the radio apparatus when the telephone receiver is taken.

from the hook, and automatically starting the radio apparatus when the telephone receiver is again placed on the hook.

The invention has further objects which are more particularly pointed out in the accompanying description.

Referring now to the drawing, Fig. 1 is a diagrammatic view showing one form of apparatus embodying the invention;

Fig. 2 is a view showing one form of magnetic circuit controlling device forming a part of the apparatus illustrated in Fig. 1.

'Fig. 3 is a view showing one form of; circuit 30 varying device forming a part of the apparatus illustrated in Fig. 1.

" Like numerals refer to like parts throughout the several figures.

I have illustrated my invention as being used evident that it might be used in connection with other electrical apparatus. In the construction shown I provide a circuit controlling device 1 which is magnetically actuated and which is placed in proximity. to. the telephone, or other electrical device, so that when the current passes through the telephone apparatus by" taking the receiver from the hook, the magnetic lines of force will actuate this controlling device to control the circuit.

In the particular construction illustrated, I have placed the controlling device 1 in proximity to the portion of the telephone circuit running through the magnet which actuates the hell or telephone signalling device 2. I have also shown I a transmitter 3 and a telephone receiver 4 on the hook 5, following the usual telephone construc-- tion, in which the circuit through the telephone apparatus is completed by lifting the receiver 4 from the hook, and is broken by hanging the receiver. 4 on the hook. i

The controlling device 1 is here shown as comprisinga magnetic needle 6, such for example a used in a compass, and pivoted at '7. One end of the needle works between the electrical conin connection with a telephone, but it is of course tacts 8 and 9. The needle itself is connected by a conductor 10, which is connected to a source of electric supply 11, which maybe of any suitable source and which I have indicated for'purpose of illustration as a battery. The conductor 10 leads to a circuit varying device and is connected with a spring contact 12 on the arm 13. This contact cooperates with the fixed contacts 14 and 15.

The contact '14 is connected by a conductor 16 with an electro-magnetic device 17,which is connected by a conductor 18 with the contact 8 of the controlling device. The contact is connected by a'conductor 19 with the electromagnetic device 20, which in turn is connected by a conductor 21 with the contact 9 of the controlling device. The arm 13 is controlled by the two electro-magnetic devices 17 and 20. In the construction shown, this arm is pivoted at 22.

The armatures 23 and 24 are associated with the electro-magnetic devices l'l and and are pivoted at 25. The armature"23 has the actuating member 26, and the armature 24 has the actuating member 27.- These members engage the arm 13 below its pivot.

It will be seen that when the electro-magnetic device 17 is energized, the armature 23 will be lifted and moved about its pivot, and this will cause the actuating member 26 to engage the arm 13 and move the lower end to the left and the upper end to the right, causing the contact 12 to move from the contact 14 to the contact 15, and causing the spring contact 28 on said arm to become disengaged from the contact 29.

When the electro-magnetic device 20 is energized, the armature 24 will be moved about 'its pivot and the actuating member 2'7 will engage the lower end of the arm 13 below its pivot 22 and move this lower end to the right, causing the upper end of the arm 13 to be moved to the left. This will disengage the contact 12 from the contact 15 and bring the contact 28 into engagement ,with the contact 29. The contact 29 has the conductor 30 connected therewith, and contact 28 has the conductor 31 connected therewith. The conductors 30 and 31 will thus have the circuit, in which they are connected, broken when contact 28 is moved out of contact with contact 29, and completed when contact 28 is moved into contact with contact 29.

This circuit, consisting of conductors 30 and 31, may be any circuit associated with the radio apparatus, the-breaking of which will shut off the apparatus, and the making of which will cause the apparatus to be set into operation, such as the direct circuit leading to the radio apparatus or the aerial and ground'circuits.

The needle 6 may be normally positioned so that its end will'be in contact with contact 9, thus insuring the contact between the needle and stop the radio apparatus.

contact 9 whenever the current in the telephone circuit ceases to act upon it.

The use and Operation of my invention are as follows:

When the device is to be used in connection with a telephone, for example, the controlling device 1 is placed in proximity with the telephone,

so as to be affected by the magnetic lines of force produced by the flow of the current through the telephone apparatus.

If, now, the parts are in the position as shown in Fig. 1, and the radio apparatus 32 is in operation, and the party having the radio apparatus desires to telephone, such party goes to the telephone and lifts the receiver 4 from the hook 5. This completes the circuit through the telephone and the lines of force acting upon the needle 6 causes such needle to move to make contact with the contact 8. This completes a circuit traced as follows:

From the source of electric supply 11 through conductor 10, the needle 6, contact 8, conductor 18, electro-magnetic device 17, conductor 16, contacts "14 and 12, conductor 10a, back to the source of electric supply. This energizes the electro-magnetic device 17, causing the armature 23 to be lifted, and this causes the upper end of the arm 13 to' be moved to the right to disconnect contacts 28 and 29 and to break the circuit through the conductors 30 and 31, and thereby At the same time the contact 12 is disconnected from the contact 14 and connected with the contact 15. The radio apparatus will stop operating and therefore, will not interfere with the telephone conversation of the party using the telephone.

When the party using the telephone finishes the conversation, the receiver 4 is placed on the hook and this breaks the circuit and causes the needle .6 to move to become-disengaged from the contact 8 and to be brought into contact with the contact 9. The circuit is then completed as follows:

From the source of electric supply 11 through conductor to needle 6, thence through contact 9 and conductor 21 to the electro-magnetic device 20, thence through conductor 19 to contact 15, and since contact 12 now engages contact lfi, the current will pass to contact 12, thence through conductor 1011 back to the source of electric supply. This energizes the electro-magnetic device 20, causing it to move its armature 24. The movement of the armature moves the upper part or the arm 13 to the left, thus connecting the contacts 28 and 29 and completing the circuit through the conductors 30 and 31 and through the radio apparatus so that the radio apparatus will then start to operating. At the same time the contact 12 is disengaged from the contact 15 and brought into engagement with the contact 14, so as to bring the parts in position to be again actuated when the receiver 4 is removed from the hook 5.

It is understood, of course, that the needle 6 is moved to make contact with the contact 8 when the talking circuit is completed in the telephone, this circuit being a direct undulating circuit.

I claim:

1. A radio controlling device comprising a switch for starting and stopping the radio apparatus, a controlling device for said switch located at a distance from the radio apparatus,

a separate electric circuit in proximity to said controlling device and which separate electric circuit electrically controls said controlling device by means of the current flowing therein, to start and stop the radio apparatus.

2.
